I am trying to fit a 10.5Kw shower. My current board is old and I can't get new MCB for it. I have just bought a new Crabtree 5 + 5 split load which I want to set up as follows:
Incoming 100A (unprotected) with cooker (32A), Heater (16A), Lighting (6A), Lighting (6A) = 60A.
63A RCCB (protected) with Shower (50A), Sockets (32A), Sockets (32A), Pond (16A) = 130A.
I am worried that the rating of the MCBs is greater than the main switches. Can anyone tell me if this is OK ?
Thanks,
Oscar.
